What is Medical Textiles?

What is Medical Textiles?

Combination of textile technology and medical sciences has resulted into a new field called medical textiles.Medical textiles are the textile products and constructions utilized for medical applications. Materials used include monofilament and multifilament yarns, woven, knitted, andnonwoven fabrics, and composite structures. The applications is huge and diverse, ranging from a single thread suture to the complex composite structures for bone replacement and from the simple cleaning wipe to advanced barrier fabrics used in operating rooms.

 
What is the classification of Medical Textiles?

What is the classification of Medical Textiles?

There are mainly four classifications in medical textiles:

  • Health care and Hygiene medical textiles.
  • Non-implantable medical textiles.
  • Implantable medical textiles.
  • Extra corporeal devices.
 
What are extra corporeal devices?

What are extra corporeal devices?

Extracorporeal devices are used to support the function of vital organs, such as kidney, liver, lung, etc. The extracorporeal device, artificial kidney  is a mechanical organ is used for blood purification and other extra corporeal devices include artificial liver and mechanical lung.

 
What are healthcare and hygiene textiles?

What are healthcare and hygiene textiles?

Healthcare and hygiene textiles materials are mainly used for protection from infections in hospital environment. They are used either in the operation theatre or in the hospital wards only for hygiene care safety for the staff and patients. A few examples are Gowns, drapes, cap, mask, etc

 
What are implantable medical textiles?

What are implantable medical textiles?

Implantable medical textiles are partly or totally inserted into the human body or a natural orifice and are expected to stay there for 30 days or more. These materials should have nontoxicity, biocompatibility and other desired properties. Yarns, fabrics, composites and 3-D shaped fabrics from woven, knitted, nonwoven, braided and embroidery play a vital role in the manufacture of various implants. Few important products are vascular graft, Hernia mesh etc; 

 
What are non-implantable medical textiles?

What are non-implantable medical textiles?

Non-implantable medical textiles are materials used for external applications on the body as a covering or an absorbent or to protect or to support injured or diseased part which helps to heal wounds or the infected site and may or may not make contact with skin. Eg: Gauze, Dressings, and Bandages.

 
What are the fibres used in medical textiles?

What are the fibres used in medical textiles?

Commonly used natural fibres are cotton, silk and regenerated cellulosic fibres (viscose rayon). Commonly used synthetic materials include polyester, polyamide, polytetrafluoroethylene (PTFE), polypropylene, carbon, glass, and so on. Biodegradable fibres include cotton, viscose rayon, polyamide, polyurethane, collagen, and alginate. Non-biodegradable fibres include polyester (e.g. Dacron), polypropylene, PTFE, carbon etc. A variety of natural polymers such as collagen, alginate, chitin, chitosan, etc have been found to be essential materials for modern wound dressings. 

 
What is the role of knitted fabric in medical textiles?

What is the role of knitted fabric in medical textiles?

Knitted fabrics provide various advantages such as extra strength without increasing thickness, high conformability, even flat structures. Thereby they found their application in Socks, Stockings, Compression garments, Tubular bandages, Finger bob, Orthosis products, Hernia mesh and Heart patches.

 
What is the role of non-woven fabric in medical textiles?

What is the role of non-woven fabric in medical textiles?

Nonwoven fabrics provide specific functions such as absorbency, liquid repellency, resiliency, stretch, softness, strength, cushioning, filtering, and use as a bacterial barrier material.The product range includes surgical gowns, masks, surgical drapes, pads; dressings; filtration materials; and implantable textiles such as tissue scaffolds for rebuilding internal organs etc. By far, most nonwoven products are used outside the body as disposable, single-use articles that have the advantage of not requiring sterilization or cleaning for reuse. 

 
What is the role of woven fabric in medical textiles?

What is the role of woven fabric in medical textiles?

Woven fabrics are mainly used for healthcare applications due to their strength, comfort ability they offer. Bed linens, pillow covers, curtains, bed spreads, surgical gowns, draw sheet, patient uniforms, bandage, gauze, medicated dressings, swabs, gauze tampon, eye dressing pad, mopping pad are the few examples.
